Thanks Dai, um still a bit confused they are good exploded diagrams but I am a novice at this dash thing and need some steps as to what has to be removed how when and where, brain must be on holidays, I have the workshop manual and it shows how to totally disassemble and reassemble just not sure if it needs to be pulled to bits or just remove 2 screws and bobs your uncle

The instrument panel has to come to pieces. If you search on 'cog' in the forum, there's been a few posts on just that problem.

If you look in the "how To" section of the Forum in downloads, there are 2 detailed posts, one in particular has step by step instructions and photos. I remember the first step after getting the speedo off the frame is removing the little knob that resets the mileage. It just pulls out, has to be done before the case can be opened.
Good luck. (put a big plastic bag over everything, there are springs and small things).

[url=http://www.servimg.com/view/18791023/90][/url]Found the posts Ta,
ok I purchased a K1100 police inst cluster from Floyd, it needs the cog that wears out but the dash is in very very good nick, I knew this when I bought it, very good price.

My speedo stopped working a few months ago which was hard to tell as when the bike is in the sun you can't see much due to the crazing and cracks have not known the time for a few years cause you can't see the clock.
It is the original dash and the bike had a minor accident before I bought it so there are a few scrapes and scratches, the dash has a few deep marks.

So which dash to fix? Or which shiney bits to use.

After my dash was disassembled the choice is easy, I will use the police dash, as mine is a mess, 3 cogs stripped an aftermarket wire with bulb inside the oil light indicator, oh and this wire is not connected to anything on the bike.

Gary, having repaired a few of these things consider the following. The smallest cog can be bought in a cluster packet from Jaycar, about $8 for the lot, but the smallest cog is the only one that can be used. The rest of the cogs are about $25 each plus about the same in postage. Theyall go brittle/melt in time because our climate... if it feels waxy or brittle, replace it. Once all have been replaced they should give you 25/30 years service.

Yes the rest of the cogs in the police dash look in good condition and clean, I have ordered the cog from Sydney for $35 inc post.

http://www.repairsonly.com.au/index.html

Now looking at the dash it has less numbers so they are a lot easier to read, sounds good to me.

The police were limited to 220km/h so I could leave them behind cause my speedo says I can do 260km/h.lol!

Just a question to anyone that may have the answer,

I missed taking a photo before I removed the dash,but there was the original connector plug (with silicone on it) and a double wire coming from a hole drilled in the back of the dash, I traced this wire back it goes for about 30cm then stops,no matching plug that I can find.

But when you pull the back of the dash it unplugs the bulb from 2nd spot down from the oilcan on the taco face, as the bulb and wire are short it would be fiddly to put back in.

There are pics above of this bulb and lead.
Anyone know what or why it's been added or will it affect something with the police dash
I think the bike used to have an alarm fitted.

Let us know when and where you do it. Very Happy We won't even quibble about indicated vs actual (GPS) speed.

Two choices with the flying bulb:

1. It was part of the alarm system
2. Someone tried to reinstate the fast idle warning light that was deleted from the later models.

My guess is (1), but either way, it isn't needed.

I suppose you could get it fromthe US..via the link from Richard's website or maybe try Otto Instruments in Brisbane. Last time I had dealings with them they wanted all theinstruments together back in the case and sent to them.

Thats an improvement, last time I spoke with Lionel Otto he was refusing to fix K instruments he must have relented under pressure.

Gary - pm me. I've just consigned a speedo to the bin as irreparable (broken needle spindle). I pulled the cogs off for you, FoC. Just as long as you don't need the tiny green one - the bastard flew across the bench somewhere and buried itself in a mixed bunch of Guzzi and BMW parts

If it is a MPH speedo the gears could be very different and with Dai being in the occupied territory then miles are still used.

There's got to be some comeback to that but I'm damned if I can think of it...
